TouchMXL內存泄漏？

Question

我使用TouchXML解析XML流的方式如下：

CXMLDocument *parser = [[CXMLDocument alloc] initWithXMLString:responseString options:0 error:nil]; 
[responseString release]; 

// array holding all the nodes 
NSArray *directionNodes = [parser nodesForXPath:@"//direction" error:nil]; 
NSArray *linieNodes = [parser nodesForXPath:@"//route" error:nil]; 
NSArray *timeNodes = [parser nodesForXPath:@"//time" error:nil]; 

    for (int i = 0; i < [directionNodes count]; i++) { 
     NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; 
     CXMLElement *direction = [directionNodes objectAtIndex:i]; 
     CXMLElement *route = [linieNodes objectAtIndex:i]; 
     CXMLElement *time = [timeNodes objectAtIndex:i]; 

     // if rows are empty, stop it 
     if ([[direction stringValue] isEqualToString:@""]) { 
      break; 
     } 

     AbfahrtszeitResult *result = [[AbfahrtszeitResult alloc] init]; 
     [result setLinie:[route stringValue]]; 
     [result setZiel:[direction stringValue]]; 
     [result setZeit:[time stringValue]]; 

     [mutableAbfahrten addObject:result]; 
     [result release]; 
     [pool release]; 
    } 

現在，我一直在「stringValue的」直插......得到了內存泄漏我做錯了什麼或者是它TouchXML？

非常感謝，

-(NSString *) linie { 
return linie; 
} 

- (void) setLinie:(NSString *)textValue { 
    [textValue retain]; 
    [linie release]; 
    linie = textValue; 
} 

-(NSString *) ziel { 
    return ziel; 
} 

-(void) setZiel:(NSString *)textValue { 
    [textValue retain]; 
    [ziel release]; 
ziel = textValue; 
} 

-(NSString *) zeit { 
return zeit; 
} 

-(void) setZeit:(NSString *)textValue { 
    [textValue retain]; 
    [zeit release]; 
zeit = textValue; 
} 

+ (NSString *) cleanUpString:(NSString *) cleanme { 
NSMutableString *tempString = [[NSMutableString alloc] initWithString:cleanme]; 
[tempString replaceOccurrencesOfString:@" " withString:@" " options:0 range:NSMakeRange(0, [tempString length])]; 
[tempString replaceOccurrencesOfString:@"&nbsp" withString:@" " options:0 range:NSMakeRange(0, [tempString length])]; 

return [tempString autorelease]; 

}

您至少有一個泄漏，你打出來的for循環不釋放你的AutoreleasePool時[[direction stringValue] isEqualToString:@""]是真實的。除此之外，我們需要查看您的AbfahrtszeitResult類的實現，以瞭解如何定義您的設置器。
